According to DASH spec (23009-1:2014): Consider a hypothetical constant bitrate channel of bandwidth with the value of this attribute in bits per second (bps). Then, if the Representation is continuously delivered at this bitrate, starting at any SAP that is indicated either by @startwithsap or by any Segment Index box, a client can be assured of having enough data for continuous playout providing playout begins after @minbuffertime * @bandwidth bits have been received (i.e. at time @minbuffertime after the first bit is received). For dependent Representations this value specifies the bandwidth according to the above definition for the aggregation of this Representation and all complementary Representations. This suggests that max bitrate should be used instead of average bitrate. Also cleaned up BandwidthEstimator code. Fixes #376. Change-Id: Ibf5896394c5c6bb820849771a2129c59202d2273 |
